I have Fedora 18 installed as the OS in my machine. I created a user called myworld. I installed the MapFish virtual environment and created a MapFish application. Now I tried to run that application using wsgi on httpd(Apache) server. I configured the python_egg_cache file to /var/www/html/python-eggs. When I launch the application it throws following error:

ExtractionError: Can't extract file(s) to egg cache
The following error occurred while trying to extract file(s) to the Python egg cache:

The Python egg cache directory is currently set to: /var/www/html/python-eggs

Perhaps your account does not have write access to this directory? You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.
I have browsed so many sites with the same issue. Unfortunately none of the solutions have resolved my issue.

later I have given full permissions(777) to that folder and still not resolved the issue.
